Refer to Table 5-2 and Table 5-3 for the specifications of the power cord and communication wire. A wiring capacity that is too small will cause
the electrical wiring to become too hot, and result in accidents when the unit burns and becomes damaged.

Select the wire diameters (minimum value) individually for each unit based on Table 5-3.
The maximum allowable voltage range variation between phases is 2%.
Select the circuit breaker that has a contact separation of no less than 3 mm in all poles to provide full disconnection.MFA is used to select the
current circuit breakers and residual current operation breakers:
